Introduction. The modern development of technology is impossible without computer technology and microprocessor technology, which directly affect the flow of various technological processes in the field of robotics. Both the improvement of computer technology and computer technology, and the development of artificial intelligence are increasingly being introduced into the technical order and successfully replacing the human resource. Practical relevance: Along with the globally increasing requirements for autonomy of actions imposed on robotic complexes with groups of unmanned aerial vehicles (hereinafter – RTK with UAVs), there is a need to build a new software, algorithmic and mathematical support in order to rationally use the available resources in organizing interaction groups of UAVs under destructive influences from a probable malefactor. Discussion: In view of the fact that its actions are almost impossible to predict and determine the exact model of its functioning, it is advisable to develop such a model that would allow taking into account all possible actions of an intruder aimed at disrupting (failing) the operation of the complex and achieving the maximum level of its information security. Such a model can be built on the well-known mathematical and software-algorithmic apparatus – blockchain technology. The modern implementation of the blockchain technology apparatus can be effectively used in the implementation of the work of the RTK and take into account situational models of the impact of the external environment on the processes of transmission and processing of information circulating in the RTK control channel, as well as provide the necessary level of information security of the system.
